git://git.linaro.org/people/mszyprowski/linux-dma-mapping
Pull CMA and DMA-mapping updates from Marek Szyprowski:
"This time the pull request is rather small, because the further
redesign patches were not ready on time.
This pull request consists of the patches which extend ARM DMA-mapping
subsystem with support for CPU coherent (ACP) DMA busses. The first
client of the new version is HighBank SATA driver. The second part of
the pull request includes various cleanup for both CMA common code and
ARM DMA-mapping subsystem."
Fix up trivial add-add conflict due to the "dma-coherent" DT property
being added next to the "calxeda,port-phys" property for the Calxeda
AHCI controller.
* 'for-v3.7' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:
ARM: dma-mapping: Remove unsed var at arm_coherent_iommu_unmap_page
ARM: highbank: add coherent DMA setup
ARM: kill off arch_is_coherent
ARM: add coherent iommu dma ops
ARM: add coherent dma ops
ARM: dma-mapping: Refrain noisy console message
ARM: dma-mapping: Small logical clean up
drivers: dma-contiguous: refactor dma_alloc_from_contiguous()

With many IOMMU'able devices, console gets noisy.
Tegra30 has a few dozen of IOMMU'able devices.

The dma_alloc_from_contiguous() function returns either a valid pointer
to a page structure or NULL, the error code set when pageno >= cma->count
is not used at all and can be safely removed.
This commit also changes the function to avoid goto and have only one exit
path and one place where mutex is unlocked.

Some highbank DMA masters can support coherent (ACP) or non-coherent DMA.
This sets up dma_map_ops for masters which are configured for coherent DMA.

With ixp2xxx removed, there are no platforms that define arch_is_coherent,
so the last occurrences of arch_is_coherent can be removed. Any new
platform with coherent i/o should use coherent dma mapping functions.

arch_is_coherent is problematic as it is a global symbol. This
doesn't work for multi-platform kernels or platforms which can support
per device coherent DMA.
This adds arm_coherent_dma_ops to be used for devices which connected
coherently (i.e. to the ACP port on Cortex-A9 or A15). The arm_dma_ops
are modified at boot when arch_is_coherent is true.

We set the capacity to zero when we discovered a device formatted with
an unknown DIF protection type. However, the read_capacity code would
override the capacity and cause the device to be enabled regardless.
Make sd_read_protection_type() return an error if the protection type is
unknown. Also prevent duplicate printk lines when the device is being
revalidated.

Now that the iSeries code is gone the backend abstraction
in this driver is no longer necessary, which allows us to
consolidate the driver in one file.
The side effect is that the module name is now ibmvscsi.ko
which matches the driver hotplug name and fixes auto-load
issues.

1. Set IDC version at start of function qla4_82xx_need_reset_handler().
2. Set IDC version only if we are 1st driver to load.
3. Added new function qla4_8xxx_update_idc_reg() to set all idc reg at one

Add "removable" module parameter to set the "removable" attribute of any
subsequently created debug block device. It is a writable driver option, so
that you can switch between removable and "fixed" media block devices in
between the add_host calls.
This is useful for being able to test the different behaviour/required
privileges in e. g. the udisks test suite.

while processing the stop firmware mailbox command on driver unload,
a interrupt is processed which causes kernel panic as the response
queue is not valid.
Fix is to clear the interrupt in free_adapter call just after
disabling the interrupts.

We always assign a dummy task context to a port in order to address a
silicon issue. We have 4 ports per controller. So when idle, there are always
exactly 4 TCs "active". The adaptive interrupt coalescing code uses number of
active TCs to figure out the coalescing values. However, we never hit "0" TCs
because of the 4 dummy TCs. Putting in fix so that we calculate this correctly.
